Improve spot-finding simple input pane

[dagewa]

This interface is weird

d_max and d_min are not parameters that are specific to electron diffraction.

In fact the "Electron diffraction parameters" title should go away entirely. The other parameter in this block is to set threshold.aglorithm=radial_profile, but some users have had success using this method for X-ray data too. DUI gives the impression that it is only for ED. Actually it is designed for data with high background with a radial fall off pattern, which is common in ED, but not limited to it.

Anyway, DUI allows to set radial_profile but not to control any of its sub-options, like n_iqr and blur. In the dials.image_viewer, selecting different spot-finding methods dynamically changes the options to set sub-parameters. It would be best to have something like this in DUI too

Current interface:

Remaining jobs

• set resolution limits using controls, not hardcoded to particular values
• have the other simple parameters adapt according to the selection of threshold algorithm (like the controls in the "Threshold info" pull down in the image viewer
